 OFFSET 1,1 COMMENTS Pálfy proved there are no primitive solvable permutation groups T with order greater than n^c_3 / 24^(1/3) but infinitely many for which equality is attained, where n is the degree of the group. Such groups necessarily have degree which is a power of 3, hence the subscript. He also gave tighter bounds for other prime powers. LINKS Table of n, a(n) for n=1..85. P. P.
